ANIMAL & CELL MODELS

	E340K, D444V, R447G, and R460G mutations in the dimer interface domain of dihydrolipoamide dehydrogenase (DLD) decrease to various degrees its activity
	under elevated oxidative stress, expression of DLD proteins with dimer interface mutations greatly accelerated the loss of respiratory function, leading to oxidative damage to the lipoic acid cofactor of pyruvate dehydrogenase and &
